I really don't understand this

As days before, I start using my blogger account by registering as a new member...The fact that I kept on forgeting my user name is actually not really true. In fact I really don't know what is mu user name, so I have problem logging in. Normal people will forget their password as for me I don't know my user name...funny, but that is the fact. I'm tired of keeping on registering and registering again..Today alone, I've done those ritual of registering twice. First one I sucessfully registered and thinking that I won't forget my user name, I log out as I need to move to another computer. When I try to log in again using what I think was my user name, I failed and now here I am after registering again finding out how to log in and how I might find my user name...
